Phenomena of M. YAMADA and T. TSUMURA

 

Table 1 shows that Mean (ME) values are smaller than 250 ms in most cases. This suggests that most subjects tapped in a faster tempo than 250 ms/tap for most conditions. Why? 

Временная разница между конкретным значением ME и 250 мсек, принятая за 1/2 периода полного колебания позволяет вычислить порядок частот субъективных времен .

 

The second phenomenon of M.Yamada and T.Tsumura is: "...the initial speed of 250 ms/tap tends to increase during the initial 100 taps. After the initial 100 taps however, IOIs seem to fluctuate centering on a relatively stable tempo. This phenomenon can be interpreted as follows: In the first stage of the tapping, the subjects searched for their own comfortable tempos, increasing the tapping speed. Once the speed reached the tempo comfortable for that subject in that condition, he or she tried to maintain that tempo uniformly".
